The 1930s

With the country reeling from the Great Depression, President Roosevelt created his “New Deal” to help America recover. The Tennessee Valley Authority was founded to help the hard-hit Tennessee Valley, where it was tasked with improving the quality of life in the region.

The 1940s

Against the backdrop of World War II, TVA launched one of the largest hydropower construction programs ever undertaken in the United States.

The 1950s

Serving as the nation’s largest electricity supplier, TVA benefited from 1959 legislation that made our power system self-financing.

The 1960s

Accommodating unprecedented economic growth, TVA began building nuclear plants to expand our capacity and spur innovation.

The 1970s–80s

A difficult decade affected by rising fuel costs led to innovative thinking about energy conservation. Working successfully to stop a steady rise in energy costs, we paved the way for a long period of stable rates.

The 1990s

Through a period of restructuring, TVA kept wholesale electric power affordable and reliable while unveiling a new clean-air strategy.

The 2000s

With power demand growing, TVA turned its attention back to clean nuclear energy, returning an idled reactor to service, and paving the way to finish construction of another. We also launched the first green power program in the Southeast.

The 2010s

We continue to carry out our mission of serving the people of the Tennessee Valley region, to make life better through our work in energy, the environment and economic development.
